You’ve counted down the days until your Las Vegas trip, watched “The Hangover” three times, and read “Casino Gambling for Dummies.“Now it’s time to pack. What should you bring to Vegas?

The Essentials:

At least one swimsuit, possibly more, no matter what time of year. In summer, the pool is the place to stay cool, whether you’re splashing in the family-friendly area or enjoying the adults-only pool club. Select your pool-side attire accordingly.

Flip-flops and comfortable walking shoes. Bare feet + hot pavement = hopping up and down. Bring flip flops to avoid doing a dance, but also throw in something sturdier. Sight-seeing on the Strip usually means lots of walking, so be sure to have comfortable shoes that won’t leave you with blisters.

A stylish outfit to wear out at night. Sure, in Las Vegas you can get away with just about any type of clothing. But if you’re going to a nightclub or a fabulous restaurant, you’ll want to upgrade from shorts and flip-flops. Some places do have dress codes, so check ahead.

Air-conditioner friendly clothing. The inexplicable rule in Las Vegas is that if it’s 110 degrees outside, the air conditioner will be set to 70 degrees in the restaurant where you want to eat. If you’re in shorts and a tank, you’re going to be cold. Any time you’re going to be inside more than outside, you’ll want to put on something a little more substantial. Bring light fabrics, short sleeves, and longer shorts.

Don’t Bother Bringing:

Heavy-duty cold weather gear. Even in winter, you can probably get by with just a good coat. Leave your parka at home.
